客户端程序运行过程中需要一直联网吗？
No. The agent connects to the internet when it finishes a work unit to upload the results as well as download a new work unit. This should take 2-3 minutes on a broadband connection and 10-15 minutes with a modem.

我如何能让程序下载完一个任务包后自动关闭网络连接？
The software does not attempt to control your Internet connection. Establishing and closing the connection is done by the operating system (Windows). If your Internet connection is staying active for an excessive period of time, go to [Start][Settings][Control Panel] and double click on "Internet Options." Click on the [Connections] tab. Highlight the dialup connection being used when the software connects to the Internet and click on [Settings]. Click on [Advanced] and check the "Disconnect when connection may no longer be needed" box.

关于端口扫描
Some users have noticed, via their software firewall, that trace-route scans apparently coming from IBM domains occur after communicating with the World Community Grid server. These are in fact normal and not someone trying to break into your machine. These are used to measure which of several paths through the Internet give the best communication performance to your machine. The servers are located in a massive hosting center, which regularly optimizes traffic between users and the servers by shifting communications among several Internet providers, depending on the destination and trace-route measurements. You can read more about this.

我应该在防火墙中为客户端程序连接网络打开什么端口？
Open ports 80 and 443, outbound.

关于反间谍软件与弹出窗口屏蔽软件
There are no pop-ups to block. Any anti-spy program which acts like an outgoing firewall would have to be configured in a manner similar to the Zone Labs settings

它会影响到虚拟专用网(VPN)吗？
This should not have any effect. The agent communicates without problems with or without VPN Client Software. Our server site is an external internet address. The bandwidth usage is minimal and equivalent to visiting a few web pages once a week or every few days on more powerful computers.

客户端程序能和 Zone Labs 一起运行吗？我应该对 Zone Labs 防火墙程序做何设置？
Yes. The agent initiates only outgoing connections on port 443 to server.worldcommunitygrid.org. This could be preconfigured as a safe zone. Alternatively, the UD.exe executable in the WorldCommunityGrid install directory could be configured to be permitted to perform this communication. However, if and when we update the agent software, it could need to be configured again. Double click on the Zone Labs icon in the system tray at the lower right. Click on "Firewall" at the left. Click on the "Zones" folder tab in the upper right area. Click on "Add >>" in the lower right. Choose "Host/Site". Select "Trusted" for the Zone field. Enter "server.worldcommunitygrid.org" for the Host name field. Enter "World Community Grid" for the Description field. Click the Lookup button. Click OK. Click Apply in the lower right. Then close the window with the X in the upper right.

为什么防火墙(我使用的是 Zone Labs)在我要连接到 World Community Grid 时总是询问我？哪里不安全了？
Firewalls, including Zone Labs, are not familiar with World Community Grid. Even though World Community Grid is safe, firewalls are designed to ask you to make the decision. On Zone Labs, just click on "Yes" to continue. You may save yourself some time in the future by optionally check-marking the message "Always allow this program to access the internet" and/or check-marking the message" Remember this answer the next time I use this program."

为什么程序无法使用我已设置好的代理服务器来连接网络？
尽管在程序安装过程中，安装程序会自动读取浏览器中的代理服务器设置，但是程序默认不使用它们。如果浏览器中的代理服务器设置是正确的，把程序设置成使用代理服务器就行了。

如何检查我使用的代理服务器是否正常？
你可以从你的浏览器中看到代理服务器的设置。在 IE 中，点击菜单“工具”-“Internet 选项”，在“连接”页中单击“局域网设置”或者“设置”按钮就能看到。如果设置了使用代理服务器，可以单击“高级”按钮获取代理服务器信息。如果您使用的是 Netscape 的话，请参看 WCG 的程序帮助文件。

如何输入我将使用的代理服务器信息？
打开程序窗口，单击一个上面有一个类似复选框的图片的按钮，或者单击登陆窗口的“Set Proxy”按钮，就可以打开设置的窗口了。在组合框中选择您的代理服务器类型，输入代理服务器地址和端口。如果您使用的是 https 的代理服务器的话，您不需要在代理服务器地址前面加上“http”。

在安装过程中填写的代理服务器信息还能更改吗？
可以。程序会自动读取 Windows 中的代理服务器设置，但不默认使用它们。您可以根据自己的需要来设置。设置好以后，记得把程序设置成使用代理服务器。

如何让程序使用我设置的代理服务器？
打开程序界面，单击一个上面有一个类似复选框的图片的按钮以显示设置窗口，在代理服务器一栏填入所需信息。
